It will be understood by those skilled in the art that all or part of the processes of the methods of the embodiments described above can be implemented by a computer program, which can be stored in a computer-readable storage medium, and when executed, can include the processes of the embodiments of the methods described above. The storage medium may be a magnetic disk, an optical disk, a read-only memory (ROM), a Random Access Memory (RAM), or the like. Embodiments of the computer program may achieve the same or similar effects as any of the preceding method embodiments to which it corresponds.
In some embodiments, the first type of files includes common files and files in a file format having a low compression space; the second class of files includes non-trivial files in a file format with high compression space.
In some embodiments, performing the first type packing operation on all the first type files, and obtaining the first type compressed packages includes: directly packaging all the first type files in an uncompressed form to obtain a first type compressed package.
In some embodiments, the second class of compression algorithms includes compression algorithms having a high compression efficiency for the respective file format; respectively performing a second type of packing operation on second type of files in the file format by using a second type of compression algorithm corresponding to the file format comprises:

and performing a second type of packaging operation on the picture files in the second type of files by using a BZIP compression algorithm.
In some embodiments, the original location information is a storage location of the file before entering the installation package; and the packing position information is the name and the address in the compression package of the file after entering the installation package.
The installation package packaging process mainly adopts the technology of adding a file management module and a classification combination compression algorithm. The core idea is to break the file directory structure of the original program before packaging. The method comprises the steps of firstly dividing an original file into an invariant file and a variable file through a file management module, then directly storing the invariant file in a corresponding directory in a compressed packet mode, classifying the variable file according to file types, dividing the variable file into formats such as a text file, a binary file and a picture file, respectively storing the variable file in different folders, and respectively compressing the different files by adopting a compression algorithm suitable for the variable file. And finally integrating the compressed packages respectively formed by compression into an installation package. Therefore, the compression rate is improved, the compression speed is improved by means of parallel compression, the volume of a compressed package is reduced, and the packaging time of an installation package is shortened.
Specifically, the original files are classified by a file management module, and all the files are classified into common invariable files and modified files. Compressing the common files and storing the files in a compressed package form; and identifying modified files through the file management module, sorting the modified files into different directories according to different types, and recording the corresponding relation between the position of the original file and the position of the file in the installation package into a text file to prepare for subsequent decompression and installation. Text, binary and picture are taken as examples, if files in other forms can be further classified, and the core idea is that one data type corresponds to one directory. When packaging, the modified file is covered into the corresponding folder in an incremental mode, so that the incremental convergence of the file is realized.
After the files are prepared according to a classification principle, a concurrent compression and packaging operation is started, if different file types want to achieve the maximum compression rate, a compression algorithm which is most suitable for the file types needs to be adopted, the text takes an actual measurement result of one project as a standard, and a text file adopts an lzma compression algorithm; the binary file adopts a zlib compression algorithm; the picture format file is compressed by bzip. If there are other types of files, the proper compression algorithm can be actually measured and selected, and a finer subdivision method can also be adopted, so that the core idea is to find the most proper compression algorithm for compressing and packaging each file. After the compression algorithm is selected, the parallel compression strategy is adopted to respectively compress the files of different types.
And finally, combining the compression packages of the unchanged files and the compression packages compressed according to different types into an installation package. Therefore, the volume of the installation package is reduced, and the packaging speed of the installation package is improved.
As can be seen from the foregoing embodiments, in the installation package packaging method provided by the embodiments of the present invention, all files in the installation package are classified into the first type of file and the second type of file by using the file management module; performing first-class packaging operation on all first-class files to obtain first-class compressed packets; further classifying all the second-class files according to the file formats, and respectively executing second-class packaging operation on the second-class files in the file formats in parallel by using second-class compression algorithms corresponding to the file formats to obtain a plurality of second-class compression packages; generating an installation engine file and writing original position information and packaging position information of all files in an installation package; the technical scheme of generating the installation package by combining the first-class compression package, the plurality of second-class compression packages, the plurality of second-class compression algorithms and the installation engine file can improve the compression rate and the processing speed and reduce the volume of the installation package.
